## Discrepancy

ON 10-5-2026, ON FINAL/LANDING INTO KDJT, THE CAPTAIN REPORTED ASYMMETRY IN THE AILERONS. THE ACFT LANDED SAFELY & WHEN PARKED AT THE FBO, CREW NOTICED RT FLAP EXTENDED & LT WAS RETRACTED. MAINT ARRIVED ON SIGHT & FOUND FLAP CONTROL ROD FROM THE FLAP SECTOR ATTACHING TO LEADING EDGE OF FLAP DISCONNECTED. CONNECTING BOLT WAS FOUND INSIDE WING & TAIL OF THE BOLT HAD BEEN SHEARED AT COTTER PIN HOLE. DETERMINED THE BOLT WAS INSTALLED INCORRECTLY WITH NO CLEARANCE FROM THE TAIL TO THE REAR SPAR OF WING. NORMALLY THE HEAD IS TOP TO BOTTOM ON MOST SITUATIONS, THIS PARTICULAR BOLT MUST BE INSTALLED "UPSIDE DOWN' FOR CLEARANCE PURPOSES & SECURED WITH A CASTLE NUT WITH COTTER PIN. BOLT REPLACED & FLAP/WING STRUCTURE WAS INSPECTED WITH NO DAMAGE. BOLT INSTALLATION/VERIFICATION ON ENTIRE FLEET WAS INSPECTED BEFORE ANY DEPARTURES ALLOWED. 1 OF REST OF THE FLEET HAD BOLTS INSTALLED INCORRECTLY. THERE WERE NO CLEARANCE ISSUES WITH ACFT. BOLTS  REMOVED & INSTALLED CORRECTLY, ACFT HAD BEEN DOWN FOR SCHEDULED MAINT.
